Dog Barn Status

The plot below shows the last twelve hours of data from the
dog barn.
The light blue shaded area (if present) indicates when the dogs
were in the barn. The orange line (and annotation) show a
variety of statistics for each plot. For barn temperature, it
shows what the temperature controller was set to. On the
humidity plot, it is the linear regression of humidity change
over the past two hours. The power line indicates the average
number of minutes the heater was on in each 15-minute period
over the period shown, and the line in the outdoor temperature
plot indicates the linear trend in temperature over the last
two hours.
